The LTC1064-3 is a monolithic 8th order lowpass Bessel filter, which provides a linear phase response over its entire passband. An external TTL or CMOS clock programs the filter's cutoff frequency. The clock to cutoff frequency ratio is 75:1 (Pin 10 at V+) or 150:1 (Pin 10 at V-) or 120:1 (Pin 10 at GND). The maximum cutoff frequency is 95kHz. No external components are needed.The LTC1064-3 features low wideband noise and low harmonic distortion even for input voltages up to 3VRMS. In fact the LTC1064-3 overall performance competes with equivalent multiple op amp RC active realizations. The LTC1064-3 is available in a 14-pin DIP or 16-pin surface mounted SOL package. The LTC1064-3 is fabricated using LTC's enhanced analog CMOS Si-gate process.The LTC1064-3 is pin compatible with the LTC1064-1, LTC1064-2 and LTC1064-4.ApplicationsAntialiasing FiltersSmoothing FiltersTracking High Frequency Lowpass Filters
